We introduced a family of highly efficient polarizing agents for dynamic nuclear polarization (DNP)-enhanced nuclear magnetic resonance (NMR) applications, composed of asymmetric bis-nitroxides, in which a piperidine-based radical and a pyrrolinoxyl or a proxyl radical are linked together.

Liquid state NMR is used to investigate surface state of CuInS2 nanocrystals (NCs). 1H and 13C NMR studies of NCs dispersed in organic solvent allowed characterizing and quantifying the ligands at the NC surface, while diffusional NMR enabled studying ligand binding dynamics.

Three different services, SyMMES, MEM and PhELIQS from INAC institute, have been working together during the last year and a half within the framework of a collaborative intern project dealing with nitrogen doped-vertically oriented graphene nanosheets (N-VOGNs) for supercapacitor applications.

In the context of the study of the interplay between magnetism and superconductivity, a phase transition has been evidenced as a function of magnetic field between two phases having identical magnetic symmetry.

The properties of hard X-ray to excite light emission can be combined simultaneously with X-ray fluorescence techniques to study nanoscale devices as demonstrated for multiple quantum well (MQW) InGaN/GaN core/shell wires integrated in blue LED emitters.

Damien Massy, SP2M/NRS, received the best presentation award at the E-MRS Fall meeting 2015 for his paper called “Alternative Smart-Cut integration on silicon”. The paper was about Damien’s PhD work, on Acoustic Emission from Crack Propagation in the Smart Cut™ Technology.

In oleaginous seeds, the energy reserves are mainly triacylglycerols that are liquid lipids contained inside micrometric vesicles, called oil bodies (OB). Seeds are of first importance for human and animal feeds, for biofuels sources and their economic weight is far from being negligible.

Graphite is widely used as an anode material for lithium ion batteries. Lithium atoms are stored with a well defined periodicity, called "stage" between carbon planes. The standard model describes the staging with pseudo-infinite lithium planes alternating with empty planes.

Mesoporous alumina (Al2O3) presents itself as a technologically important material due to its high surface area and catalytic properties. However, the characterization of this material remains elusive to various techniques.
